DUMPING-CAR. l

SPECIFICATION forming part of Letters Patent No. 284,691, dated September 111883.

Application filed April 24,1883. (No model.)

the accompanying drawings, and to letters of4 reference marked thereon, which form a part of this specification.

` My present invention is au improvement on the inventions set forth in the following-named United' States Patents issued tofme, namely: No. 193,101, dated July 17, 187 7 5 No. 199,761, dated January 29, 1878; No. 200, 813, dated February 26, 1878, No. 236,121, dated December 28,1880, and No. 244,954, dated July 26, 1881, and it relates to the construction of the car-bed, the trucks, and transoins, to the construction of the rockers, and means whereby the car, after dumping, shall right itself up again 5 to a device for preventing` the separation of the car-bed from the trucks; to the mechanism for dumping at either side of the car;l to the side bearings and their application so as to keep the car-bed in position and prevent undue friction while th'e car is moving around curves of the track; to the levers 'and hand-wheel for working the side bearings; in

combining` the shaft and worm-gear with aboX or frame within which such worm is inclosed; in means for permitting` a sudden dumping when needful, and in other particulars hereinafter set forth.

In the drawings only such parts are illus trated as are necessary to understand the in- Vention. e

Figure 1 is an elevation of part of a dumping-car, showing some of my improvements; Fig. 2, a transverse view, partly in section, showing the rockers and adjacent parts; Fig. 3, a cross-section through the end platform; Fig. 4, a plan, showing certain parts on the under side of the car bed or body, and Figs. 5 to 12, inclusive, are detail views.

Referring to Fig. 2, which is a transverse section, a a. is a piece of timber, placed underneath and between the intermediate stringers,

b c d e, and immediately over the trucks atV either end of the car.

It is fastened to place, as shown, by bolts f, which run through the stringers and timbers, all being for the purpose of strengthening the car. rIhese pieces a, thus connected and fastened to the stringers, support and sustain them, and the end boards, f3, of the box onbody portion ofthe car (at either of its ends) are placed a sufficient distance from the end ofthe car floor or frame to allow plenty of space for the mechanism on the dumping-shaft at such end of the car, and also plenty of room for the person working such mechanism. XVhile this construction shortens somewhat the holding or carrying capacity of the car, this loss of space is well compensated for in giving this ample platform for the workman to 'dump the car, and also in affording room for pieces f2, of wood or iron, placed lengthwise of the car, and secured to it by bolts or otherwise, and against or on which, whenr the car is tilted or dumped, the workman may secure afirm foothold or brace. These two features of giving plenty of room for the workman and for the mechanism to be worked by him, and of preventing his sliding off or being thrown from the car when upsetting it, are of great practical importance.

The ,upper and lower transoms of the carbody are shown at h and i. The lower one, z', is made of two pieces of steel or iron, each about three inches in width, and placed side by side at, say, about six inches apart, and are Yof the shape shown in Fig. 2-that is, they are bent at each extremityA to extend a little way under the outside sills, j j, as shown at 1. 'Ihence they extend upward on the inside of such sills (being bolted to them at 2) to the top of said sills. l Thence they extend a short distance on a level with the car-sills, and thence 'downward under the intermediate stringers,

b c d c, where they are in the form of an arch and constitute part of the rocker 7c, as hereinafter described.

The upper transom, 71., consists of one or of two pieces, lm, of steel or iron, placed on top of the car sills and,l stringers and over each truck. If made in two pieces, these pieces are placed side by side, as shown 1n Fig. 9. This IOC transom is held in position by bolts running through it, and through the stringers I) c d c,

and through the timber a under these stringers, and also through the lower transenne'. The bolts running through the top transoms and through the stringers have nuts on their lower ends, and incisions or openings in the upper rocker-casting, g, may be made to receive such nuts and to permit them to be put on and drawn down to place. The bolts running through the llower transoms, c', have nuts on the tops of the stringers, as shown, and the bolt-heads are countersunk in these transoms i, as shown, for the purpose of leaving a smooth under surface on the rocker. Notches u are made in the upper transoms, 71 where they are secured to the outside car-sills, for the purpose of allowing the side doors, fn, of the car to swing over the door and against the transom when the door is closing, and to prevent the door swinging inward beyond the proper line.

The lower rocker, or, rather, the arched bed for the upper rocker, is shown at o. It is placed on top of the bolster p on each of the car-trucks. It is made of iron or of wood, and with an opening, q, in its top to receive the projection r (which preferably should taper) on the lower side of the upper rocker. The opening q extends entirely through the arched bed o, and is preferably made a little longer in one direction than in the other, as shown, to facilitate the rocking of the upper rocker when tilting the car. rlhis bed o has also two projections, s s, against which the square ends t t of the upper rocker-casting g may strike or abut in order to form a bearing -when the car is tilted. The projection r is long and strong, and, in connection with the opening q, serves as a kingbolt, and prevents the car-bed separating from the trucks when the car is in transit, and it likewise permits the tilting for dumping, while the projections 819, besides offering a positive barrier against the car shifting laterally out of place when tilted, also lend l their assistance to its righting itself up again when emptied, as they form fulcrum-points for the car-body when tilted, and the greater leverage would necessarily be at the raised side of such body.

The upper rocker should be about six inches vwide on its lower side, and also where it is placed between the lower transoms, i, directly over the rocker-bed o, and it vshould be about twelve inches or more in width above Ythe lower transorns, it being bolted by one or more bolts running lengthwise of the car, the whole being for the purpose of. combining the rocker bolster.v The linked chain w being fastened at one of its ends to one of the plates a',"it then is passed up over one of the guide-pulleys z, which are fastened to the inside of the outside sills or to the floor, then over two stringers, over another guide-pulley, z, and then down and around a cog-wheel, 3, which is` fastened to and which operates the shaftc, and so on in ya similar manner over corresponding guidepulleys to the opposite side of the car, where its other end is secured to the other plate x. The guide-pulleys should be made with fiat surfaces adapted for the flat links, and with a deep annular groove to receive the edges of lthe intermediate links, which would be in an edgewise position, or at right angles to the other links, such pulleys and chain being of patents, a small friction wheel or roller, 4, at

their bottom, to prevent undue friction when the car is moving around, curves of the track.

The upper v end of each side bearing is hung on a bolt, 5, which passes through ears or projections 6, which form parts of a piece ofcasting, 7, these castings being severally bolted to the lower side of the stringers b and e, respect ively, at each side of the car over the trucks; but to preventthese side bearings from being strained, or from working in adirection endwise of the car, they are each braced and sustained by iron or steel rods 8 8, which are connected each, by an eyebolt or equivalent device, to the Stringer, so as t0 permit the side bearings to be swung up and down on the bolt 5 when required, but not to swing or sway or be strained in the line or direction of the length of the car. These side bearings are operated or raised by rods or chains 10, which are attached to both the side bearings, which are on the same side of the car-that is,.to those at each ofthe trucks--said rodsor chains being extended, and at their ends attached by an endless chain to the shaft 11 of the handcranks 12, the rod or chain being connected also to cross-levers 13, which are fastened to the intermediate stringers at or near each end of the car by bolts`13 l, the other ends of each of such levers being connected by this endless chain, which passes down over a pulley fastened at or near the floor, and is connected to the side bearing, this endless chain being guided over pulleys. By these means both side bearings on the same side of the car are acted upon simultaneously by the working of one of the hand-cranks 12. flhe side bearings on the other side of the car are operated in a similar manner by similar devices by means of the other hand-crank 12 and its couplings.

On the end of shaft t is the cog-wheel 3,

IOO

IIO

which gears with the teeth of the cog-wheel 1410i the worm-wheel 15, (this cog-wheel and worm-wheel being in one piece.) rIhe wormwheel engages with a worm, 16, which is inclosed in a cast or wrought iron box, and issecured to the lower end of a shaft, 17, which is worked by a hand-crank, 18. Vhen this crank is turned, its worm 16 turns the wormwheel 15, and with it, necessarily, its cog-wheel Io 14, which is integral with it, and this wheel 14 imparts motion to the cog-wheel 3 and its shaft o, and thus the car is dumped to either` side, as desired, and the load is discharged. An iron or steel hinged box, 19, entirely closed 15 at its top, covers the worm and gear wheel 14 15 and protects them from dirt. It also permits the ready oiling o'f the parts and the disconnection of the cog -wheels 13 and 14 when it is desired to dump suddenly. This 2o box 19 is held to the floor by any suitable means, such as straps of iron at its sides. It extends from 2() to 21, and is hinged at 21, where it is beveled to permit its being raised when desired. A lever, 22, connectswith this box by means of suitable straps, 23, and on lifting this lever it lifts the entire box 011 its hinges at 21. The box maybe fastened down by the straps 24, secured to the iioor or stringers at each side of the box, and by a bar or 3o bolt passing through such straps. When the box is lifted by the handle, (or handles, if desired,) the cog-wheel14, which is journaled in this box, is also lifted, and thus disengaged from the cog-wheel 13 on shaft o, and this disengagement allows the car, after it has been tilted beyond the center of gravity, to dump suddenly, without any restraint from such cog-'wheel or from any of the devices which actuate it, such suddendumping being, 4o as is well known, very important in order to loosen and throw out quickly and with a thud any sticky matter-such as soft-'i ron ore, moist gravel, or mud-which cannot be discharged completely by any gradual or slow easy tilting.

The worm 16 is placed in its position in its box, sliding it in through any appropriate side opening into which a portion ofthe periphery of the worm-wheel 15 projects; and in order 5o to oil it and keep it oiled, I place several sharppointed upright wires, 2S, in its box or casing, and on or between such wires I place sponge, cotton waste, or other good absorbent to hold oil, with which it is saturated, thereby keeping this worm well oiled as the sponge touches this worm, a suitable opening, of course, being made for placing such sponge, &c., on the pins, and this opening being covered by a suitable door or piece of iron, 29, on a hinge, 30, 6o and which door protect-s the sponge or waste, as also the inclosed mechanism, from cinders,

dirt, Ste. The opening over the worm-wheel 15 is also covered by a door or piece of iron on a hinge at 31,'to protect it from dirt and cinders. These devices are placed as seen on the enlarged platform at one end of the car, and are thus readily accessible, while plenty of room is afforded for their manipulation.

The side doors, n', of the car open automatically and atl the proper time, and by any of 7o the modes and means described in my former patents, in order to allow the load to be discharged.

The trucks are strengthened in the following manner: A bolster, p, is made, say, about 7 5 ten to twelve inches in its cross-section. At each of its ends it is notched out, as seen at 33, to leave a space for the spring or trucks to be placed between `the bolsters, and at the places where they are notched a bolt, (or bolts,) 8o 34, is placed through the bolster, to strengthen it and prevent its splitting off, a truss-rod,

35, extending across the car and placed on each side of the bolster. A saddle, 36, at the middle of the bolster to hold the truss down, is also put on the bolster to strengthen it, the rods being at their ends fastened to the bolster at its top, and then to the saddle at its bottom. This construction strengthens the trucks sufficiently to enable them to sustain any load that 9o may be put on the car. 1

'I claimj 1. In combination with the car, the movable side bearings, 4, provided not only with a wheel or roller, 4', at the lower end, to prevent 9 5 undue friction when in transit, but held in position at their'point of suspension by a bolt and ears, as described, and braced by swingrods 8, hung on the stringers and operated by appropriate devices, all substantially as and for the purposes described.

2. In combination with the iron transoms t', constructed as described, the lower transoms, h, made as described, and forming part of the center bearing and upper rocker of the car.

3. In combination with the platform on the end ofthe car, as described, the worm 16, compound gear and worm wheel 14 15, their iron or steel box, and a shaft, fu, with cog-wheel 3 at or near its-end, all for the purpose of dumping or tilting the car-bed, as described.

4. In combination with the cog-wheel 3 on shaft fu, the hinged metallic box serving to protect the gearing', and also `serving to support the bearings of the compound gear 14 15, and whereby the gears 14 and 15 may be disconnected at will to permit sudden dumping.
